Traffic doesnt show, building radius doesnt show

[trojan_47 2]

The game will not show me the radius of schools, hospitals, etc. when I am preselecting them, and evaluating them. They appear only after the building is placed. There is no traffic, no matter what options I toggle on or off. The only traffic I see is when I dispatch police or fire. I know this is a technical issue not an in game option issue. Also when zoning the zone colors dont like like they are supposed to when the game is operating correctly. (I have played the game on multiple pc's so I know.) They seem duller and more generic.

I am using a gateway m series laptop purchased in 2008 with Vista x64 and over 2ghz P4 duo core and 4 gigs of ram.

Has anyone been through this or know how to fix it?

I seem to remember it happening a LONG time ago on on of my desktop pc's with XP. I seem to remember being able to fix it. thats why this is killing me. If anyone could help me, I would love to see traffic again.

If the visual effects are set to low, then the radius of buildings won't show, but I'm pretty sure that doesn't affect the zone colors or the traffic.
